How do I run a landing-page / 'fake-door' test?

The short answer

Put up a simple page that describes the offer as if it's real, drive a bit of targeted traffic to it, and measure whether people take a costly-to-them action, sign up, pre-order, join a waitlist, or click 'buy'. Intent you can measure beats opinions you can't.

Why we picked it A YC partner turns 'talk to users' into a repeatable 5-question interview script you can use this afternoon. It's The Mom Test compressed into a lecture, perfect if you want the method fast before reading the book.

How to Talk to Users

On YC Startup Library by Eric Migicovsky (YC / founder of Pebble) ~25 min

  • Don't pitch your idea, you'll bias every answer.
  • Anchor on the last time they hit the problem, and what they did about it.
  • If they've done nothing to solve it, the problem may not be painful enough.

How to Plan an MVP

On Y Combinator (YouTube) by Michael Seibel (YC) ~13 min

  • Talk to users before you build anything.
  • Launch something lean in weeks, not months, the goal is to start the feedback loop.
  • Don't try to solve every problem for every user; ship narrow and ugly.

Why we picked it The most famous fake door in startup history, the three minute video that grew Dropbox's waitlist from a few thousand to seventy five thousand overnight before the product was ready. Watch it to see that the door does not have to be a page: a video demoing a product that barely exists can measure real intent through waitlist signups. Note how it was aimed at exactly the audience most likely to sign up.

  • A demo video can stand in for a product that is not built yet
  • The waitlist signup was the costly action that proved demand

Why we picked it Michael Seibel, who ran YC, makes the blunt case for shipping something almost embarrassingly simple and learning from real users instead of chasing a perfect first version. His line that if it takes more than a month to build, it is not an MVP is a practical yardstick for anyone stuck polishing. Watch it when the urge to add one more thing before launch takes over.

How to Build an MVP

On Y Combinator Startup Library by Michael Seibel ~10 min video

  • An MVP is the fastest way to start learning what users actually want, so its job is speed to feedback, not completeness.
  • Keep the first version ridiculously simple: if it takes more than about a month to build, you are overbuilding.
  • The fear of losing customers to a rough product is usually overblown; you learn far more from shipping than from refining in private.

Why we picked it An Indian founder story where the early demand test was manual, cold emails and direct outreach to find the first customers before the product had proven itself. It is a grounded counterpoint to the landing page: sometimes the fastest way to measure intent in a B2B market is to ask people to commit directly. Useful if your buyers are enterprises who will never fill in a consumer style waitlist form.

The Mom Test

  • Talk about their life, not your idea.
  • Ask about specifics in the past, not opinions about the future.

Why we picked it The free, original essay that defined the MVP before the book existed, written plainly by the person who coined the term. It clears up the most common mistake founders make, which is thinking an MVP has to be a working product when a landing page or a video often teaches you more, faster. Useful as a quick primer you can send someone in one link.

Why we picked it The canonical fake-door test, told by the founder who ran it. Buffer started as a two-page site: one page pitched the tool, a pricing button led to an email capture, and every signup got a personal note. Real demand, real conversations, a paying customer in weeks, and not a line of product code.

Why we picked it Todd Jackson studied how dozens of now-large companies validated their very first idea. The pattern that repeats: deliver the outcome by hand, talk to real users, and watch for genuine emotion. A polite 'that's cool' is a no. Strong reactions are the signal you want.

Why we picked it A clean, practical playbook for the mechanics: where to place the door, what to measure, and how to avoid annoying the people who walk through it. It covers the in product version (a button for a feature you have not built) alongside the standalone landing page, so you see both shapes of the test. Good for turning the concept into a concrete plan you can ship this week.

Why we picked it This is the most concrete walkthrough of how to test a niche when you have nothing built yet: put up a page describing the offer and count who actually clicks or signs up. It treats a click as a behavior, not an opinion, which is exactly the difference between real demand and polite interest. It gives you the seven steps, rough benchmarks, and the ethics of an honest reveal page, so you can run it this week for almost no money.

Fake Door / Smoke Test

From kromatic.com by Kromatic (The Real Startup Book) ~15 min read

  • A click or an email is a behavioral signal, worth far more than someone saying they like the idea
  • Set your success threshold and sample size before you start, so you cannot rationalize a weak result
  • Be honest on the reveal page ("coming soon, join the list") so the test does not burn trust in your own niche

Why we picked it A builder to builder account from someone who ran the test on their own idea, with the honest distinction that a landing page validates the idea, not the product. It is a useful reality check: signups prove interest in the promise, but you still have to prove you can deliver it. The comments thread adds real founders debating what a good conversion rate actually looks like.

Why we picked it GV's method for building a realistic facade and testing it with five target customers in a single week, which is the interview flavoured cousin of the fake door. Their fake it philosophy, a convincing front is all you need to learn, is the same principle as a landing page test applied face to face. Use it when you want qualitative reactions to a prototype alongside the quantitative click data.

Why we picked it This is the founder essay that made the case for validating before you build, from the person who did it with Buffer. Gascoigne frames the no-code or landing page MVP not as a shortcut to a product, but as a way to learn whether anyone actually wants the thing, which is exactly the stance this question takes. His honest point is that 120 signups plus real conversations taught him more than any polished build would have.

How to successfully validate your idea with a Landing Page MVP

From Medium (Joel Gascoigne, co-founder of Buffer) by Joel Gascoigne

  • The goal of a no-code or landing page MVP is validated learning, not vanity signups: talk to the people who respond, do not just count emails.
  • Anything can be your MVP as long as you are genuinely testing demand before committing to a full build.
  • Buffer got only 120 signups in seven weeks, but the direct conversations proved real interest and led to paying customers at launch.
